I got the error after I executed the following command as below document says.

Can I ignore the below error? I am wondering if there is any solution.

cd home/service/consoleme/ui
yarn start

Hi @adenkang , what version of yarn and node are you using? Can you try upgrading to the latest LTS releases? Here are the versions I have. After upgrading, remove your node_modules directory and try running yarn again to install frontend packages.

✗ yarn --version
1.22.19

✗ node --version
v15.14.0

✗ node --version
v15.14.0

✗ yarn
yarn install v1.22.19
